I must admit that I have shortened the text excessively because I did not want to go on and on.
In truth, the spiritual vision is acquired by taking refuge in Krishna, God, the Supreme Person, by totally abandoning himself to Him, serving Him with love and devotion, obeying Him, doing all His will with joy and eagerness, and by strictly applying the regulatory principles:
Not having illicit sexual relations, outside marriage (the ideal is not having sexual relations at all, because this act causes reincarnation), not eating meat, fish and egg, not consuming drugs, exciting products such as tea, coffee, cigarettes, alcohol, and not gambling.
It is therefore essential to lead a regulated spiritual life, i.e., austerity, Krishna meditation, and Krishna consciousness at all times. The Supreme Lord gives us a sublime remedy for this purpose, which enables us to resist the onslaught of material life, materialism, and the influence of the energy of illusion which plunges human beings into permanent error. This sublime remedy is the chanting of His Holy Names, the sound of which is spiritual, for this chant has spiritual origins.
In truth, the Holy Names of God composing the song Haré Krishna are specially intended to counteract the terrible consequences of the present age, the dark age, the age of discord, hypocrisy, quarrels, indifference, decadence and sin. There is no method of spiritual realization for the present age so sublime as this song in Sanskrit:
Hare Krishna, Hare Krishna, Krishna Krishna, Hare Hare
Hare Rama, Hare Rama, Rama Rama, Hare Hare
This song in Sanskrit of the Holy Names of God means:
O Lord, O source of all happiness, please make me your beloved servant.
Krishna and Rama are the first two Names of God, and Haré is none other than his internal energy, his energy of bliss. This sublime song allows among other things:
To eliminate all the sins accumulated in all our previous lives from material existence, to purify the defiled heart, to be delivered from imprisonment in matter, (the material body) in this world, to obtain spiritual knowledge, to progress and bring forth all forms of devotional service, to awaken his love for Krishna, God, the Supreme Person, to taste spiritual happiness, to obtain the company of God and to devote oneself to his devotional service of love as if one were to immerse oneself in the waters of a great ocean of love and to reach, whatever the situations, certainly the supreme perfection. It is enough to recite or sing harshly Krishna without offending, so that the stain of the present age and the various sufferings that overwhelm us disappear in us, allowing us to regain our original spiritual body, what is the true resurrection, and to return to Krishna, in our true home, in his infinite and absolute kingdom.
